Abstract
A primer detonator comprises an ignitron, a hollow rubber pillar, a gunpowder ignition pillar, a first ignition pipe, a delay cord, a second ignition pipe and a foundation detonator, wherein one end of the gunpowder ignition pillar is connected with the hollow rubber pillar, the other end of the gunpowder ignition pillar is connected with one end of the first ignition pipe, the ignitron is inserted into the cavity of the hollow rubber pillar, two ends of the delay cord are respectively inserted into the cavities of the first ignition pipe and the second ignition pipe, delay gunpowder is filled in the delay cord, the outer layer of the delay cord is covered with a heat insulation sleeve, and the foundation detonator is spliced with the second ignition pipe. The primer detonator has a good warning function in work, and has the advantages of being simple to operate, high in stability, lower in cost and high in safety degree.
Description
Technical field
The utility model relates to blasting material field, especially relates to a kind of detonating capsule.
Background technology
In the down-hole, when place controlled blasting such as open pit quarry and tunnel, tunnel piercing and engineering explosion; Generally adopt two kinds of detonation modes of electric cap and Nonel detonator at present; These two kinds of detonation modes all need extend longer electric wire or detonator; As adopt electric detonator initiation, in some cases, exist couple current, static, radio frequency, direct current and alternating current, the thunder and lightning etc. of stray electrical current, high-tension bus-bar to bring harm to shotfiring safety like the explosion scene; As adopt comparatively safe Nonel detonator detonation mode, and detonator may be scratched by hard rock, injure by a crashing object, intakes in the process of extending, and the reliability that influence is detonated needs long detonator simultaneously, and the cost height that detonates is less economical.
Detonating capsule is the detonate detonator of blasting network of a kind of novel being exclusively used in.Be used for the various Nonel detonators of direct initiation, primacord and commercial explosive, be applicable to the controlled blasting and the engineering explosion in places such as no biogas, mineral dust explosion dangerous down-hole, open pit quarry and tunnel, tunnel piercing, and be used for secondary and separate big gun.
Patent CN201348470Y discloses a kind of safety-type long delay detonating capsule; Input port and output port are arranged on box body; Input port, output port communicate with inner chamber, and the extension rope is placed in the inner chamber, and extension rope one end is connected with blasting cap; The extension rope other end is connected with detonator, in the extension rope delay powder is arranged.Because of its extension rope coiling is placed in the box body, the heat insulation and dissipation weak effect, security is affected, and manufacturing cost is high in addition, and is not strong to the adaptability of environment.
The utility model content
In order to overcome the defective of prior art, the utility model technical problem to be solved is, a kind of detonating capsule is provided, and it has high safety reliability, adaptability widely, and cost is lower, easy to operate simple.
In order to solve the problems of the technologies described above; The basic fundamental design that the utility model adopts is: a kind of detonating capsule, comprise ignitron, hollow rubber post, igniting powder column, first ignition tube, extension rope, second ignition tube, basal detonator, and an end of said igniting powder column is connected with the hollow rubber post; The other end of igniting powder column is connected with an end of said first ignition tube; Said ignitron inserts in the cavity of hollow rubber post, and insert respectively in the inner chamber of first ignition tube and second ignition tube at the two ends of said extension rope, is filled with delay powder in the extension rope; The skin of extension rope is coated with thermal sleeve, and the said basal detonator and second ignition tube are pegged graft.
Further, said thermal sleeve is a fiberglass pipe.
Further, said thermal sleeve skin is coated with protecting tube.Be provided with protecting tube and help protecting the extension rope to avoid the external condition interference, have functions such as good anti-mechanical damage, waterproof, thereby improve security of products and reliability.
Above-mentioned improvement project can be implemented alone or in combination.
The beneficial effect that the utility model brings: be provided with the hollow rubber post, can locate detonate pin or detonation element easily, be easier to operation; Be provided with the igniting powder column, can improve the reliability of igniting; Couple together through will light a fire powder column, extension rope, basal detonator of first ignition tube, second ignition tube, improved the reliability of detonating capsule; The skin of extension rope is coated with thermal sleeve, has improved the safety of products performance.Have good alarm function and security reliability during this product operation, the characteristics simple to operate, that stability is high, cost is lower, safe coefficient is higher of detonating.
Description of drawings
Fig. 1 is an embodiment detonating capsule structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.Detonating capsule embodiment illustrated in fig. 1; Comprise ignitron 1, hollow rubber post 2, igniting powder column 3, first ignition tube 4, glass fibre thermal sleeve 5, extension rope 6, protecting tube 7, second ignition tube 8, basal detonator 9; One end of said igniting powder column 3 is connected with hollow rubber post 2; The other end is connected with an end of said first ignition tube 4, and said ignitron 1 inserts in the cavity of hollow rubber post 2, and insert respectively in the inner chamber of first ignition tube 4 and second ignition tube 8 at the two ends of said extension rope 6; Be filled with delay powder in the extension rope 6; The skin of extension rope 6 is coated with glass fibre thermal sleeve 5, and glass fibre thermal sleeve 5 skins are coated with protecting tube 7, and the said basal detonator 9 and second ignition tube 8 are pegged graft.
When detonating; To detonate pin or detonating cord inserts in the hollow rubber post, and charging is detonated, can the firing point stick; The igniting powder column delay powder in the delay powder that ignites; Through the length control time-delay length of delay powder and extension rope 6, the delay powder output is ignited basal detonator, thereby realizes the process that whole igniting, time-delay are detonated.
The above is merely the preferred embodiment of the utility model, and limits the utility model never in any form, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit and principle that the utility model claims limit, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
